The sun would be 4 times less bright than it is now. The brightness of the sun follows an inverse square law

How bright does a star appear from earth?

It depends on its intrinsic brilliance and its distance from the observer


A bright star can appear dimmer than a less bright star if the bright star is?

If the bright star is located farther away from Earth than the less bright star, it will appear dimmer due to the inverse square law of light intensity. The amount of light reaching Earth decreases with distance, so a closer, less bright star can appear brighter than a further, brighter star.


Why are other stars not bright like the sun?

The other stars do not appear as bright as the sun because they are much farther away. Even the closest stars apart from the sun are hundreds of thousands of times farther away. In terms of actual brightness, some stars are brighter than the sun.


How does the moon appear to an observer on earth during a full moon?

Full, large or whole. Maybe the question was meant to be...How would the Earth appear to an observer on the moon during a full moon?


Is it true that two stars that have the same brightness are the same distance from earth?

Not necessarily. Two stars can have the same brightness but be at different distances from Earth. The distance of a star affects how bright it appears to us, so a closer dim star may appear as bright as a farther bright star.


Is the closer a star is to earth the brighter it is?

Yes. A star that is closer to us will appear brighter than if it were farther away. However, stars also vary in their actual brightness, so how bright a star appears depends on both how far away it is and how bright really it is.


How can a star give off the most light and not be the brightest in the sky?

How bright a star appears depends on both its actual brightness and how far away it is. The farther away a star is, the dimmer it appears. A bright but very distant star many therefore appear dimmer than a less bright star that is closer to us.


What is the relationship with brightness and distance with stars?

Other things being equal, if a star is farther away, it will look less bright. This is the same with any light - if you move farther away from the light, it looks less bright.


How does the sun appear to you?

um really bright


Why The Moon and the planets appear bright at night?

The Moon appears bright at night because it reflects sunlight. Planets appear bright due to the reflection of sunlight off their surfaces, as well as their own internal heat that emits light. Additionally, planets are much closer to Earth than stars, making them appear brighter in the night sky.


Why stars are not as bright as the moon?

In terms of actual brightness the stars are much brighter than the moon and some are even brighter than the sun. They only appear dim because they are much farther away than either the sun or the moon.


Why Some stars appear to shine more brightly than the others?

The stars vary in both how far away they are and in actual brightness. The closer a star is to us, the brighter it will appear. Stars also vary in actual brightness. For example, the brightest star in the night sky is Sirius. It appears bright because it is both a fairly bright star (about 25 times brighter than the sun) and is one of the closest stars to us at 8.6 light years away. The nearest star visible in the night sky, Alpha Centauri, is about half that distance but does not appear as bright because it is far less bright than Sirius in actual luminosity. Conversely, Sirius also appears brighter than Betelgeuse which is actually much brighter than Sirius but also much farther away.
